Mini-DVI to VGA - online video freezes when dragged from MacBook to LCD TV

I connected my MacBook to my LCD TV this morning via Mini-DVI to VGA, and am trying to stream online video. The video works fine when the browser is on my MacBook screen, but when I drag it over to the LCD TV, the video freezes. I tried setting the screens to mirrored as well, and the video wouldn't play (on either). I'm not really sure what else to try. Any help would be appreciated!

Try this...
With the TV connected, go into Displays Preferences and click on the Arrangement tab. You should see two blue rectangles meant to represent the two screens. One of the rectangles will have a white bar across the top, meant to represent the menu bar. Drag the small white bar from one blue rectangle to the other. This will move the real menu bar to the TV, making it the primary display. Now see if your video will play on the TV.

Mini DVI to VGA Adapter Video Problem

This year at Randolph-Macon College we replaced the Math lab Emac computers with IMac G5 Intel machines. The laboratory has an NEC model MT1050 projector with a manufacturer’s date of August 2002. We can not seem to get rid of ever present scan lines. We can slow them down and speed them up by adjusting resolution and refresh rates, but nothing will remove them. We are connecting the IMac to the projector via the Apple Mini-DVI to VGA Adapter. It is specifically designed for use with the iMac (Intel Core Duo), and the adapter connects to the Mini-DVI port of the computer and the VGA end of the adapter to an external VGA monitor or projector.
Troubleshooting the problem we have swapped IMac Intel computers with no luck, but we still have to use the Apple Mini-DVI to VGA Adapter. When we hook the projector to a Intel Mac Book Pro, we have to use a different adapter, but then it works perfectly. In fact, everything we try using other adapters works fine, it’s just when we use the Apple Mini-DVI to VGA Adapter that we experience the video problem.
Has anyone experienced this problem and if so, have you been able to remedy it?
iMac (Intel Core Duo) Mac OS X (10.4.8)

I don't have much to suggest, except to ask if you can try with a different mini-DVI to VGA adapter. (i.e. do you have more than one on hand to make sure yours isn't just defective?) Make sure it is firmly seated into the iMac.
I use the same adapter to provide an extended desktop on an old CRT monitor and the display is great.

Connecting Macbook via mini-dvi to vga (s-video) to Dell 24 inch monitor

I'm connected but, the screen does not look good at all. I can barely read the text.
I tried connecting via the rca cable and the s-video cable - but both are blurry. I checked the settings, but the maximum setting doesn't even go to 1920x.... at all.
Another option on the monitor is a DVI cable. Do I need a mini-DVI to DVI adapter instead? Or is there a setting somehow to make the s-video connection much better.
My monitor is a Dell 2405FPW.

Tele is right. If you are mirroring the same image on both displays, you will never get more resolution than the lower resolution display.
If you instead create an extended desktop where you can view different content on both your MacBook screen and the external monitor, then you CAN set different resolutions for both screens. The MacBook's internal LCD is only 1280x800, but the MacBook can do 1920x1200 resolution on an external monitor per the specs here: http://www.apple.com/macbook/specs.html
If you're doing this right, the display should be sharp and crisp. But you definitely want to be using a DVI or VGA cable, and NOT s-video or RCA/composite. Do you have a mini-DVI to DVI cable? Here it is: http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore?productLearnMore=M93 21G/B
DVI is sharper than VGA is sharper than S-video is sharper than RCA/composite.

Videos freezing when streaming from router

When i stream higher resolution videos to my TV or PC, from the usb stick attached to my router(linksys EA4500). The videos freeze, then playes again, then freeze, etc. I have no problem with lower res. videos or music. Could there be a firmware update to solve this problem, or is it a hardware issue?
regards, jorgen.

I don't know how to check if the tv can see the 5 ghz. The internet on the TV works flawlessly.
regards, jorgen.
I see. It is better to connect your TV to the 5 ghz network if the TV can see it. 5 ghz is designed for video streaming. Since your accesing or viewing high resolution vidoes from the Virtual USB, the TV should be connected to that network. What firmware are you using? Are you using the Classic Firmware or the Cloud Firmware?

Video freezes when switching from window mode to full screen mode

I have seen repeatedly that when I play a video (downloaded via iTunesU) and try to switch to the fullscreen view, the video freezes at the frame I hit "fullscreen" on. The audio, and the file, however, continue to play but the video is frozen. To fix this, I have to keep hitting Pause/Play for the video to resume. It also happens when I go back to windowed mode.
Any solutions?

Same problem, as soon as I 'upgraded' to 9.03.15. At first I thought it was only a problem with older videos, but as I checked out videos, even a recently downloaded TV show exhibits the problem. Some videos, however, work fine? If I play around with a problem video until I get a green screen I can get it to work.

Apple TV 2 choppy video playback when mirroring from Macbook Pro (Yosemite) and Macbook Air (Yosemite) but not iOS devices

Video playback is choppy (cuts out every 30-45 seconds) when air playing from both my MacBook Air 1.3 GHz Intel Core i5 running Yosemite and my husbands new MacBook Pro, but runs perfectly when mirroring from any of our iOS devices (iPhone 6+, iPad mini 3, etc.) We have Apple TV 2. This problem just started a few weeks ago, was working fine around Christmas. The problem seems to have coincidentally started right after our son tried plugging in and setting up his Chromecast on our tv. I disconnected the Chromecast, but we still have the problem. All of our software if up to date and I've tried disconnecting blue tooth, we do not have a microwave and our wifi network has a very strong signal. We have an Airport Extreme base station. Is there a solution to our problem?

Hi leahmturner,
I see that you are experiencing an issue with choppiness while AirPlay Mirroring from your computers to your Apple TV. I have an article that contains some helpful troubleshooting steps for you regarding this issue:
About AirPlay Mirroring in OS X - Apple Support
http://support.apple.com/en-us/HT201343
Optimizing image quality
Resolution matching modes
You can choose between two desktop resolution matching modes that let you select which display will have the best image. When AirPlay Mirroring is turned on, select an option under "Match Desktop Size To:" in the AirPlay Mirroring menu extra.
Match Desktop Size To: Apple TV
AirPlay Mirroring changes the desktop resolution to best match your Apple TV, resulting in a 16:9 image that fills the HDTV screen. This setting often produces the sharpest image on the HDTV. The aspect ratio and/or resolution of the built-in Mac display may change to accommodate the Apple TV.
Match Desktop Size To: This Mac
AirPlay Mirroring scales the contents of the desktop to fit on the Apple TV, leaving the resolution of your Mac's display unchanged. Use this setting for the sharpest image on your Mac's display. Depending on your Mac model, the resulting image may not fill the HDTV screen.
Troubleshooting AirPlay Mirroring
If you don't see mirroring options
If your Mac and Apple TV are on the same network, but no AirPlay Mirroring menu appears, your Apple TV may be asleep. Simply press a button on your Apple TV remote to wake it up. After a few seconds, the AirPlay Mirroring menu extra appears. If you still don't see the options you expect, make sure your Apple TV has the current software update installed. Also make sure that you have the "Show mirroring options in the menu bar when available" option selected in the Displays pane of System Preferences.
If the menu bar or Dock is cropped
Some HDTVs have bezels that cover a small percentage of the screen. This can result in a slight cropping of a full-resolution HDTV image. Depending on the HDTV model, AirPlay Mirroring may automatically adjust the picture size to prevent cropping. If you are using OS X Mountain Lion or later, and you see cropping of the menu bar or Dock when using AirPlay Mirroring, toggle the Overscan correction option in Displays preferences.
Minimize video post-processing
HDTVs often apply picture quality enhancements intended to improve the look of film and video sources. In some cases, these enhancements can lead to over-sharpening artifacts when displaying your Mac desktop. Some HDTV models have built-in settings to change or disable the enhancements for use with a computer (computer, presentation, or game modes). Otherwise, the controls for sharpness, detail enhancement and noise reduction can be used to optimize the appearance of the Mac desktop. Consult your HDTV’s manual for guidance on the appropriate settings for use with a computer.
Firewall security settings
If you use a firewall, make sure the following firewall security options have been set to allow AirPlay Mirroring to work:
Choose System Preferences from the Apple menu ().
Click Security & Privacy, then click Firewall.
Click the lock icon to unlock it if it's locked, then type an administrator name and password.
Click Firewall Options.
Deselect (uncheck) the “Block all incoming connections” checkbox.
Select (check) the “Automatically allow signed software to receive incoming connections” checkbox.
Thanks for coming to the Apple Support Communities!
Regards,
Braden

Mini-DVI to VGA connector resolution isses.

Hi all.
I have a Packard Bell 19" Monitor that supports 1440x900 75hz Resolution and bought a Mini DVI to VGA cable to connect it to my MacBook(Late 2007). When I attempt to calibrate its resolution there is no 1440x900 option at all. Ive read online that this is due to the VGA adapter? Is this true? and would I be better swapping my adapter for the mini DVI to DVI adapter (Which I would rather not use as my windows desktop connects to this thus equaling more faf.)

VGA maximum resolution I think is about 1200 x 800. If you want 1440 x 900, DVI to DVI would be the best way to achieve this. KVM switches, and A/B boxes exist for DVI that would allow your PC to share with the MacBook the display.

Mini-DVI to VGA frustrations

I have a mini dvi to vga adapter connecting a CRT to my macbook, everything was working great untill... it turned pink, everything on the display has a really bad pink tint, ive tryed it with different displays... no luck...
So I call apple care to see if i can get it replaced, the lady i talked to could barely speek english, but thats not important right now. She tells me that my macbook is out of the phone support unless i buy apple care, then she transfers me to sales once she finds out that its a bad display adapter. At sales i explain what was wrong, and the guy there sends me back to apple care, i hung up.
I want to know how the heck i can get this fixed, i bought the display adapter like 2 months ago, they should be able to replace it. Where do i go from here?

Others have had problems with the adapter:
"If you order one of these treat it very gently, be careful how you pack it when traveling, etc. My first one broke in 4 months (the wires internal to the rubber cable enclosure shorted - so the screen would drop out certain colors)."
from <http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/6394003/wo/Nl1 WlaKtWDNh2CU6rLDioTOQHl2/3.0.0.21.1.0.8.11.33.0.0.1.1.0.9.1.1.0.1.11.7.10.0#rev>
Explain to Apple that it is a bad adapter (still in warranty), not your computer.

Mini-dvi to vga to YPbPr

Hi. I have an Intel-based Macbook (mini-dvi) and I bought an LCD-TV which has a VGA and a Y/Pb/Pr input. I was planning on using my mini-dvi to vga adapter to connect my mac to my Trutech lcd-tv/monitor. My question is whether it is worth going through all this trouble. With which connection (VGA or Component Video in) will the quality of the image change significantly?
thx

Actually, I bought it on Friday. I knew it was cheap quality because it is a no-name and it is from Target. I bought it for 200 $ so I didn't expect much (Will be used in my college dorm anyways).
This is the one: http://losangeles.craigslist.org/lac/ele/488030589.html
I just want to get the most out of it.
If you recommend me a better one for approx. 200$, I would bring the cheap one back in a second.

Mini DVi to VGA : impossible to display to a video projector

hello !!!
I bought a MINI DVI to VGA adaptor and i as soon as i connect my videoprojector (Sanyo) to my Imac with the mini DVI-VGA adaptor, my Imac screen freezes and nothing appears on the video projector screen.
What can I do ?
Thanks

Not exactly, though you can reset the PMU of an iMac flat panel machine with a PowerPC G4 processor, reset the SMU of a G5 PowerPC-equipped platform, or reset the SMC of one driven by an intel processor.
Any corrupted settings stored which might affect your external video will be dealt with by those processes. Have you attached the adapter alone and seen this same outcome, or does it occur only when a VGA projector is attached to the adapter?

No video signal using mini dvi to vga adapter.

I just bought a macmini,the last generation. Separately I bought on the apple store a mini dvi to vga adapter because when I bought the macmini I forgot to buy that....once the adapter arrived I tried to turno on the mini,everything seems to be normal,the mini works,the audio signal is normal and after the startup it asks me to choose the language,but the screen says there's no INPUT SIGNAL. I tried another mini dvi to vga adapter,the vga wire works with my pc so I didn't try another one,I tried the reset of the mini,nothing....do I have to try with "miniport to vga" adapter or is there something else I can try?

I got my Mac Mini yesterday and I am having the exact same problem as you are having.
I've tried on two different TV's but it is just not sending a signal. Is it faulty?

Help! Syncmaster 1100 blurry when connected to Imac with Mini DVI to Vga

Hi,
I recently tried to use my Samsung SyncMaster 1100 (21") as a secondary display But when I connect it with the mini dvi to vga adapter to my imac the image looks blurry. Is there some compatibility isue with syncmaster 1100?
Please Help!, I tryed the imac with a different secondary monitor and it works fine. I tested my syncmaster with another pc and it works fine. I don't know what else to do.
Thanks in advance

Hi Josh,
To start, it is considered extremely impolite to type in all capital letters as you have done. Please use all lower case, or preferably properly capitalised text, in future.
With regards to the problem you're having.. the reason you only see the desktop background is due to screen spanning. If you want the external display to display the same thing as the internal display, go to the displays system preferences pane, and check the box that says "Mirroring"
The color problem is probably due to a loose connection somewhere, either between the iMac and its adaptor, the adaptor and the cable to the projector, or between the projector and the cable plugging into it. If you're still having problems, try different adaptor cables, or try plugging it into a different monitor to try to work out which one is causing a problem.
Good luck

Apple Mini DVI to VGA Adapter

I purchased a Apple Mini DVI to VGA Adapter for my MacBook (early 2008).
When I plug the cable into my MacBook it works fine, I have to drag the browser from my macBook onto my LCD using the curser. But when I do this with iTunes and I want to watch a film or music video there is no sound. Does anyone have any ideas of how to solve this problem or if im using it right.
Please help.

Ah. Okay. Well you need to output the sound from your MacBook to your TV. You need another cable to carry the audio. You can use an 1/8 mini audio to TOSLINK (if your TV supports optical audio input) or 1/8" to RCA audio (those red/white cables).

Mini- DVI to VGA adapter Or is that, DVI to DVI?

I am having difficulty figuring out which adapter to purchase if I want to use my MacBook to make a Keynote or PowerPoint Presentation with an LCD projector.
Do I need the Mini- DVI to VGA adapter, or is it DVI to Video adapter, or DVI to DVI adapter? Good grief! I've made fabulous-looking slides and just want to take my computer to the lecture hall, connect it to their projector, and give my talk. How does one decide which cable to get, if I don't know for certain what kind of projector they are using?
Aren't all LCD projectors standardized this way?
Thanks for the clarification.
~ john

As mentioned, VGA is much more common than DVI is on projectors, so the mini-DVI to VGA will certainly work more often than the mini-DVI to DVI will.
It costs $19USD, so I would get both and use the best option available to you when you get to the location and see what kind of projector they have.
You also may want to pack the VGA and a DVI cable just in case. You never know if the location will have one on hand, or if it gets misplaced just in time for your arrival.

Mini-DVI to VGA maximum resolution?

I have an external monitor with only VGA input, and it's resolution is 1680 x 1050. Will my MacBook be capable of using this display at it's native resolution using a mini-DVI to VGA adapter?
The display is the HP w2007v in case anyone is interested.
Thanks

Hi Josh,
taken from Apple Video Developer Note found here:
http://developer.apple.com/documentation/Hardware/Conceptual/HWTechVideo/Articles/Video_implementation.html#//apple_ref/doc/uid/TP40003994-SW741200331181
External Display Modes
The default display mode setting on the MacBook is extended desktop display. To toggle between the two modes, press the F7 key, or go to System Preferences>Displays>Arrangement.
A scaling function is available when the internal display and an external monitor are both operating and the mirror mode is selected. However, the external monitor could have black borders during mirroring, depending on the supported timings between the two displays and on the monitor’s selection algorithm. Black borders are not seen on VGA displays.
Both displays show full-sized images when the display resolution for the external monitor is set to the internal display’s native resolution: 1280 by 800. Both displays can operate with other resolution settings, but in mirror mode, one of the displays may be smaller than the full screen and have a black border around it. With the resolution for the external monitor set to less than 1280 by 800, the image on the internal display is smaller than its screen. For resolution settings larger than 1280 by 800, the image on the external monitor is smaller than its screen.
In mirror mode, the maximum size of the external display is 1280 by 800 at 60 Hz. In extended desktop mode, the maximum size of the external display is 1920 by 1200 at 60 Hz.
So in extended mode the 1680x1050 resolution should be avaiable.
Hope it helps
Stefan
